Tambahkan Objek Garis ke file PDF

Potongan kode berikut juga bekerja dengan pustaka Aspose.PDF.Drawing.

Tambahkan objek Garis

Aspose.PDF for .NET mendukung fitur untuk menambahkan objek grafik (misalnya grafik, garis, persegi panjang, dll.) ke dokumen PDF. Anda juga mendapatkan keuntungan untuk menambahkan objek Garis di mana Anda juga dapat menentukan pola garis, warna, dan format lainnya untuk elemen Garis.

Ikuti langkah-langkah di bawah ini:

1. Buat PDF Dokumen baru.

2. Tambahkan Halaman ke koleksi halaman file PDF.

3. Buat instance Grafik.

4. Tambahkan objek Grafik ke koleksi paragraf dari instance halaman.

5. Buat instance Persegi Panjang.

6. Atur lebar garis.

7. Tambahkan objek Persegi Panjang ke koleksi bentuk dari objek Grafik.

8. Simpan file PDF Anda.

Potongan kode berikut menunjukkan cara menambahkan objek Persegi Panjang yang diisi dengan warna.

    var dataDir = RunExamples.GetDataDir_AsposePdf_Images();

    // Create PDF document
    using (var document = new Aspose.Pdf.Document())

        // Add page
        var page = document.Pages.Add();

        // Create Graph instance
        var graph = new Aspose.Pdf.Drawing.Graph(100, 400);

        // Add graph object to paragraphs collection of page instance
        page.Paragraphs.Add(graph);

        // Create Line instance with specified coordinates
        var line = new Aspose.Pdf.Drawing.Line(new float[] { 100, 100, 200, 100 });

        // Specify dash settings for the line
        line.GraphInfo.DashArray = new int[] { 0, 1, 0 };
        line.GraphInfo.DashPhase = 1;

        // Add line object to shapes collection of Graph object
        graph.Shapes.Add(line);

        // Save PDF document
        document.Save(dataDir + "AddLineObject_out.pdf");
    }

        var page = document.Pages.Add();

        // Create Drawing object with certain dimensions
        var canvas = new Aspose.Pdf.Drawing.Graph(100, 400);

        // Add drawing object to paragraphs collection of page instance
        page.Paragraphs.Add(canvas);

        // Create Line object
        var line = new Aspose.Pdf.Drawing.Line(new float[] { 100, 100, 200, 100 });

        // Set color for Line object
        line.GraphInfo.Color = Aspose.Pdf.Color.Red;

        // Specify dash array for line object
        line.GraphInfo.DashArray = new int[] { 3, 2 }; // Dash and gap lengths in points

        // Set the dash phase for Line instance
        line.GraphInfo.DashPhase = 1;

        // Add line to shapes collection of drawing object
        canvas.Shapes.Add(line);

        // Save PDF document

Gambar Garis Melintasi Halaman

Kita juga dapat menggunakan objek garis untuk menggambar salib mulai dari sudut Kiri-Bawah ke Kanan-Atas dan sudut Kiri-Atas ke Kanan-Bawah.
